Specification of Letters Patent.

Patented July 25, 1916.

Application filed September 29, 1913. Serial No.792,410.

T all "whom it may concern Be it known that we, OLIVER \V. JOHNSON and"VILLIAM A. READE, citizens of the United States, and residents ofCleveland, county of Guyahoga, State of Ohio, have jointly invented anew and useful Improvement in Typograph-Machines, of which the followingis a specification, the principle of the invention being hereinexplained and the best mode in which we have contem plated applying thatprinciple, so as to distinguish it from other inventions.

The present improvements, relating as indicated to typograph mechanism,pertain more particularly to the so-called Ludlow typograph in which themeans for casting the type-bars or slugs, comprise a body of matrix barsadapted to be distributed, or moved relatively to each other, so as tovariously aline the duplicate series of matrices which they carry, andthus compose any desired word or series of words. In the simpler form ofthe Ludlow typograph, the bars are shifted by hand, the only mechanismthat is provided, aside from the casting mechanism proper, comprisingmeans for insuring the proper alinement of the distributed bars and forlocking them during the casting operation.

The present improvements have as their object theprovision of a simplekeyboard mechanism whereby the manual handling of the bars just referredto may be obviated, thereby rendering the operation more convenient andat the same time increasing the speed with which the type bars may beset up and cast.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanisin embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings :Figure 1 is a plan view of the composingmechanism of our improved typograph; Fig. 2 is a view similar to Fig. 1,but with the keyboard mechanism and other parts removed so as to showthe arrangement of the matrix bars; Fig. 3 is partly an end elevationalview and partly a. transverse section of the mechanism, the plane of thesection being indicated byrthe line 3-3, Fig. 1-; Fig. 4 is a frontelevational view of the same the lefthand portion of the mechanism beingomitted; Fig. 5 is a transverse sectional view taken on the planeindicated by .the line 55,-Figs. 1 and 2; Fig. 6 is a transversecross-sectional view of arportion ofthe mechanism as indicated-by thesection line 6-6, Fig. 1; Fig. 7 is a section of the same detail in ahorizontal plane as indicated by the line 7 7,'Fig. 6; Fig. 8 is asection of such detail at right angles to the'section of Fig. 6, asindicated by the line 88, Figs. 1 and 6; Fig. 9 is a transverse verticalsection of another part of the mechanism, as indicated by the line 99,Figs. 1, 2 and 4; Fig. 10 is a side elevation, Fig. 10 a bottom planview, and Fig. 11 a top plan view of the bar moving and settingmechanism; Fig. 12 is a section at right angles to that of Fig. 9, asindicated by the line 10-10, Fig. 9; Figs. 13 and 13 are sideelevations, and Fig. 14, a plan view, both on a larger scale than Figs.1, 3 and 4, and showing a detail of the key-board mechanism proper; Fig.15 is a rear elevational view of the mechanism showing certain poweroperating means; Fig. 16 is a part elevational and part sectional viewof a detail of this mechanism, as indicated by the line 16-16, Figs, 1and 2; and Fig. 17 is a rear elevational view of said detail, viewingthe same from the left in Fig. 12. i

The general supporting frame for the mechanism constituting the presentimprovements is not illustrated, but merely the bed plate or top 1 ofsuch frame, which is utilized as the base or support for the mechanismherein involved The frame proper, it may be explained, is also utilizedto support the casting mechanism for the slugs or typebars made from thematrix provided by the present typograph mechanism proper, as will bemore fully explained, but such casting mechanism forms no part of thepresent invention, and accordingly only so much of it is shown as isnecessary to an understanding of the composing mech anism.

In fact such casting mechanism, so far as shown, consists merely of acasting pot 2 suitably mounted below the bed plate 1 which supports thetypograph mechanism of present interest so as to be capable of bringingits nozzle or spout 3 (Fig. 12) into proper cooperative relationshipwith the mold 4: wherein the slug or type-bar is formed, when metal issupplied thereto from such pot. Such casting pot spout is terminallyclosed by a squirt-plate 5 that is designed to be brought directlyagainst the under side of the mold when desired, and then removed so asto permit such mold to be lowered from the bed of the machine in :orderthat the slug may be ejected there- When in position for casting in thefashion just described, the mold 4 is designed to register with anopening 6 in the bed plate 1 such opening being disposed transversely ofa longitudinally extending depression or trough 7 in such bed, and it isover the mold, when in this position, that the matrix bars 8 aredesigned to be placed in properly distributed fashion so as to provide acomposite matrix of selected characters directly over the slot 9 in saidmold. Such mold is designed, of course, to fit snugly in the opening 6in the bed plate and with its upper face flush with the bottom of thetrough, so that the bars may be longitudinally moved across the samewithout impediment.

The detailed construction of the matrix bars need be only briefly noted.The major portion of such bars, or, as illustrated, the entire bodythereof, are preferably made of laterally tapered form, the taper beingcontinuous from one end to the other end, as shown for example in Fig.2. The matrices 10 are struck in, or otherwise formed on, the loweredges of the bars, regarding the latter as they rest on the troughbottom or equivalent support (see Figs. 9 and 12); while their upperedges are provided with transverse grooves 11 corresponding in positionwith such matrices, such upper edges being further provided with aseries of characters (not shown) that likewise correspond with suchmatrices.

In their normal inoperative position the body of bars is divided intotwo groups as shown in Fig. 1, with their larger, or butt, ends directedoutwardly, and their inner, or pointed ends, directed inwardly. The ribs12, forming in effect end walls for the trough 7 that supports the bars,serve stops to limit the outward movement and determine the location ofthe inner ends of the bars, when thus assembled in normal position. Suchinner ends are designed in this position of the bars to lie on oppositesides of the casting slot 9 in the mold 4 when in place in the bottom ofthe trough, being engaged by the oppositely inclined faces of a block 13that is slidably mounted, so as to be adjustable transversely of thetrough in line with such casting slot, said block being supported ingrooves, or ways, 14 formed in the bed of the machine. The inner end ofthe block is preferably flattened as at 15, such fiat face forming ineffect an adjustable abutment,'or front wall, to the trough, betweenwhich and the rear fixed wall 16 of such trough, the bars 8 aredistributed incidentally to the composing operation which will bepresently described. This slidable block 13 is designed to fitsufficiently tight in the ways 14 to remain in whatever position it isleft; it may, however, be advanced inwardly, with a step by stepmovement, by the action of a normally inoperative pawl 17, which isadapted to be actuated by a lever 18 as will be readily un derstood. Apin 19, removably fitted in a suitable hole in one of the ways 14:,serves as a stop to normally determine the amount that block 13, may beretracted. By taking out such pin, however, the block is free to moveoutwardly until it reaches the ends of its ways.

The spaces between the block and the respective ends of the trough areclosed by movable walls in the form of bars 20 of substantially the samelength as the matrix bars. The inner ends of these bars slidably contactwith the corresponding incline-d faces 21 of the block, while theirouter ends 3 are attached to spring-pressed plungers 22 extendingtransversely into the trough, the tendency of each plunger being toforce the corresponding movable wall-member against the adjacentcollection of bars and thus force the latter in turn against the rearwall 16 of the trough 7.

In distributing the bars 8 for composing matrices over the casting slot,the innermost bar of first the one collection and the other 3 is movedinwardly (that is from one body 1 toward the other) so as to advance itsthin end until it contacts with the corresponding inclined face 21 ofthe block 13; such face will then guide the end in question toward 2 therear wall 16, either directly into contact with such wall in the case ofthe very first bar, or in contact with such bars as may have beenpreviously interposed. The bars are thus advanced outwardly fromopposite 1 sides and are moved varying distances, de-

pending on which matrix character on the under face of the bar it isdesired to locate over the casting slot. As clearly shown in Fig. 2, thebutt end of any such advanced bar acts as a fulcrum as it were for theadjacent collection or body of undistributed bars, so that the action ofthe corresponding spring-pressed plunger 22 is to maintain suchundistributed body of bars at all times i in compact form with theirthin ends close together and resting on the corresponding inclined face21 of the block 13.

As successive bars are advanced and left in selected position, the block13 will be forced gradually away from the rear wall 16, until eventuallyenough bars have been brought across the casting slot to compose a fullline, or approximately a full line. In order to provide for space in theline thus formed, as between successive words, or at the end of theline, blanks are left between the matrices at different points on theunder edges of the bars, as at 23, Fig. 12, and in addition the thinextremities 24 are left blank for a certain distance back from the end.If a space of predetermined width is desired, a selected blank 23 isbrought over the casting slot. For the purpose of justification,however, a blank of adjustable width is required, and this is obtainedby overlap ping two such thin ends 24, just sufficiently to insure thebars sliding past each other.

The determination of the space thus pro vided for may then be left untilthe line is completed, or substantially completed, when, by forcingtogether such paired bars, the space can be entirely filled and the linethus justified. The block 13, moreover, can be forced in, to clamp theassembled bars very tightly, by actuating the lever 18, in the finalcasting operation.

Supported over the trough 7 so as to be movable transversely of the sameis a movable platform or carriage 25, Figs. 1, 3, 4 and 5. Such carriageis slidably supported at its respective ends on guides 26 formed in thebed plate 1 of the machine, and this carriage, which in effect bridgesthe trough 'from end to end, serves to support the keyboard mechanismand other parts more or less directly connected with the shifting of thematrix bars in the trough, as will presently be described.

The primary means for distributing the bars comprise a device which isadapted to positively engage with successive bars in the respectivegroups collected at each end of the trough and move such bars toward thecenter, the keyboard mechanism being arranged to cooperate with suchpositive act ing device to release each bar when it is brought into apredetermined position.

The primary distributing device just referred to, as designed for movingand set ting the bars, consists of a pair of oppositely disposed fingersor catches 27 of the form clearly shown in Figs. and 11, such catchesbeing pivotally attached near the respective ends of a bar 28 slidablymounted on the carriage near the latters rear edge and capable ofmovement parallel with such edge. Each such catch 27 is formed with arecess 29 adapted to hook over a projection in the form of a pin 30 inthe butt end of a matrix bar 8, and thus temporarily connect theshiftable bar 28 that carries the catch, with such matrix bar for thepurpose of shifting the latter. For operating the catches, anoscillatory lever 31 is provided pivotal about an axis 32 and having alost motion connection with the inner ends of two rods 33, the outerends of which are respectively connected to toggle levers 34, which inturn are adapted to actuate said catches, the arrangement being suchthat when a rod is actuated outwardly it will straighten the toggle withwhich it is connected and thus depress the catch to engage the pin on abar located therebeneath. Un-

due straining of the toggle is prevented by a pin 35 which will allowthe joint to bend only so far. Conversely, inward movement of either rod33 will bend the corresponding toggle and raise the catch connectedtherewith so as to release the pin onthe bar engaged by said catch.

The slide 28 which carries the catches 27 is reciprocated, preferablyautomatically, by power means at a predetermined rate of speed, and tothis end a second reciprocable slide in the form of a rack 38 isprovided on the upper face of the bed of the machine and to the rear ofthe trough 7, such-rack being actuated in the specific structureillustrated in the drawings by an arrangement of gear ing shown indetail in Fig. 15. This gearing comprises a pinion 39 disposed to engagethe teeth of the rack and adapted to be driven from a power shaft 40carrying a short lever 41 that is connected by a rod 42 to oscillate asegmental gear 43. The latter is connected by means of a pinion 44,pulleys 45, 46 and a chain 47 to communicate its motion to the aforesaidpinion 39. Obviously the segmental gear will be alternately oscillatedin opposite directions, and this motion will be translated intoacorresponding reciprocation of the rack bar through its engagement withsaid pinion. A clutch 48, operable by a hand-lever 49, is adapted toconnect or disconnect the lever 41 with the shaft 40, as desired.

The range of movement of the rack 38, is

such as to carry it from the position illus- T trated in full lines inFigs. 1 and 2, where it is shown as lying for the most part at the rightof a transverse median line of the machine, to a corresponding positionon the other side of such median line. of movement, in other words, issufficient to carry the slide 28 and catches 27 back and forth, so thatthe catches will alternately be enabled to engage with the pins on thebutt ends of the bars at the respective ends of the trough.

The connection between the rack and the slide is designed to be suchthat not only will such slide be moved in unison with the rack, butmeans are also provided for im- Such range L held a rod or bar 51, theforward end of which is adapted to detachably engage with a somewhatsimilar bracket or standard 52 mounted on the slide 28. Such forward endof the rod is provided with a pin 52 terminating in a knob and forming aconvenient handle whereby the rod 51 may be secured in a bayonet slot 54in said bracket 52 when desired, and at the same time quickly and easilydetached if the operator wants to separate the slide and carriage fromthe rack.

The side of the rod 51 which is disposed downwardly, when it is inposition where the pin '53 engages the bracket 52 on the slide, isprovided with serrations 55 that are adapted to be engaged by a pawl 56pivotally attached to the rear face of said bracket. Such pawl normallyis carried out of such engagement, but as the rack is reciprocated aroller 57 attached to the pawl alternately engages with lugs in the formof flat springs 58 disposed at the proper distance on either side of thetrans verse median line of the machine, which springs raise the pawl andcause it to engage the rod and move the same forward one notch. Suchmovement of the rod produces a corresponding transverse movement of thecarriage or platform 25 and is arranged to take place following therelease of a bar by one of the moving and setting catches and before theother of said catches reaches the end of its travel so that it can bepositioned to engage the next bar.

The detailed construction of the keyboard mechanism may be understood byreference to Figs. 13 and 1 1-, the first of said figures showing atypical key lever in several dif ferent operative positions. In thescheme illustrated, it is intended that there shall be one key or keylever 60 for each character on the matrix bars, including the blanks onsaid bars having a predetermined width for spacing purposes. In additiontwo keys 61, one at each end of the board, are utilized to set bars withmerely their thin ends overlapping, as is required for justifying, and,as a matter of fact, provision is made for locating ust double thenumber of matrices on a single bar, by reason of the reverse arrangementof the matrices on the bars belonging to the two groups of oppositelydisposed bars. However, a. single key can be utilized to locate onecharacter on one bar and another character on another bar, the operatorhaving merely to note from which end of the machine the bar is beingmoved inwardly in order to select the proper set of characters on thekeys.

The keys 60 are mounted in banks, or tiers, on the carriage or platform25, preferably centrally thereof, as shown in Figs. 1 and 4. Associatedwith each key, is a transversely reciprocable locking member 62,: whichsaid key is adapted to force rearwardly when it is depressed, while themember in turn is adapted thereupon to lock such key in its depressedposition The individual key, shown in Fig. 13, appears in its normalraised position, and the plan view of Fig. 1 1 corresponds with Fig-13in this respect; in Fig. 13, however, the key lever is shown depressedand the locking member shifted into its rearmost, or operative.position. In such depressed position of the key lever 16, its rear end65 is tilted upwardly into position to engage the lever 31 on the slide28 as the latter is reciprocated.

Similarly the locking member 62 in its rear-1 most position is adaptedto engage a fixed lug or cam 64 that projects forwardly from the slide28 and lies directly beneath the lever 31. The effect of the engagementof the rear end of the key lever with lever 31 on the slide is tooscillate the forward end of such last named lever in a directionopposite to that in which the slide itself is moving at the time. As aresult of such 0scillation the catch 27 at the trailing end of the slidewill be raised from the position shown at the right in Fig. 10 to thatshown at the left of said figure. The effect of the engagement of thelocking member 62 with the fixed lug or cam 64 on the slide, is to forcesaid member forwardly into its normal position. Since this returnmovement of the locking member will be completed before completion ofthe oscillation of the lever 31 by the rear end of the key-lever,

such rear key-lever end is provided with a projection 66 that is adaptedto rest on top of the lever 31 until the latter has entirely passedbeyond the range of action of the key lever. Thereupon, the member 62,having been restored to its normal position as just described, the keylever will drop back into its normal position.

The locking member 62 carries a leaf spring 63 that projects forwardlyand en gages a downwardly projecting lug or heel 67 on the key-lever,such heel lying forwardly of the pivotal axis of the key-lever so as totend to retain the latter in its normal position. This spring has anoffset at the point where it thus engages such heel,

,so that the rearward movement of the locking member may be derived fromthe action of this heel on the spring. The rear end 65 of the lever isfurthermore beveled so as to exert a cam-like action on said lockingmember to assist in forcing the latter back into operative position. Thelocking member it should finally be noted, has a raised face 68 which,in such operative position of the member, is located beneath the rearend of the key-lever and thus positively retains the latter in itsdepressed or operative position. The operator in using the key-boardmay, accordingly, depress a selected keylever and then proceed with theselection of the next key'lever, since the first keylever will belocked, by the means just described, in position to release the matrixbar then in course of movement by virtue of the engage ment of a catch27 on the reciprocating slide 28 with the pin in such bar. Such release,and the restoration of the key-lever and its corresponding lockingmember, are all accomplished automatically, thus affording ample time tothe operator to set another key before the direction of movement on theslide is reversed, incidentally to positioning the next matrix bar.

. For effecting the engagement of the catches 27 with the pins at thebutt ends of successive bars, various means may be employed; forexample, a simple inclined cam face (not shown) may be disposed at eachend of the carriage or traveling frame which supports the key-board,with which cam face said catches may engage, as the limit of movement ofthe slide is reached. Preferably, however, I employ relativelystationary elements in the form of two pins 69 (see Figs. 1 and 4)mounted on the upper face of the. carriage or frame, one on each side ofthe bank of key levers, these pins lying in the path of movement of thelever 31, and their location being so determined that they will engagesuch lever just before the end of the slides movement in a correspondingdirection is reached. Such pins 69 respectively serve to oscillate thelever 31 so as to drop the catch at the forward end of the slide (havingregard to the direction of movement of the latter) and over the pin onthe outermost matrix bar in the adjacent group of bars. It will beobserved that the recesses 29 in the catches 27 are of sufficient extentlongitudinally to insure engagement of the catch with such pin, even ifthe depression of the catch is not timed with absolute accuracy. Theunder sides of the catches are furthermore grooved as shown at 29 inFig. so that the catch will ride up over the pin, even if it isprematurely dropped.

For forcing together the bars which may be left with their ends merelyoverlapping, in order that the assembled line of assembled matrices maybe justified, as also for reassembling the distributed body of bars intothe two separate groups above described, we provide what may be calleddriving and reassembling mechanism. Such mechanism consists of twohandled plates 70 supported by traveling carriages 71 on a bar 72 thatis pivotally attached or hinged to standards 73 disposed to the rear ofthe rack 38 and lying parallel therewith and with the trough 7. Normallythe bar 72 is tilted into vertical position, as shown in Figs. 1, 2 and4, in which position the blades likewise are turned up vertically out ofthe way. The operator, however, may readily seize the handled portionsof the blades and turn them down over the bars in the trough, as shownin Fig. 3, assuming the carriage or platform to have been movedforwardly so as to uncover the bars and trough. When the blades are thusturned down they are adapted to engage the pins 30 on those of the barsdisposed for use in justifying as aforesaid, and by pushing said bladestoward the center, the necessary \vedging action is readily produced.

Conversely, after the casting operation, when it is desired to restorethe bars to their initial positions, these blades 7 0 may be broughtclose up together at the center of the machine and turned downinside thepins of the bars which have been brought forward from their normalpositions, even within the pins of those which have been broughtfarthest forward as shown in dotted outline Fig. 12. By then moving theblade outwardly the pins on all of such distributed bars will be caughtup and the bars carried along until theirbutt ends are brought againstthe ribs 12- which form the end walls of the trough, thus restoring eachgroup of bars into the normal assembled condition in which the majorityof them are shown in Fig. 2.

Obviously there will be more or less of a tendency present for the barsthat have been located in selected positions by the joint action of thereciprocating catches 27 and the keyboard mechanism, to be displacedfrom such positions by the successive movement of adjacent bars, and itaccordingly becomes desirable to provide means for retaining the bars insuch positions. To this end a memher is provided similar in its actionto the comb-like composer .frame of the Ludlow typograph, said memberconsisting of a bar 75 supported from the rear of the carriage orplatform and in parallel relation thereto, sufficient space being leftbetween the same and the platform proper to accommodate said catches 27and their supporting and actuating mechanism. Bar 75 is provided on itsunder side with a series of transverse grooves 76 corresponding in theirspacing with that of the matrices on the matrix bars. Such grooves areadapted to engage with the pins on the successive matrix bars.immediately after such bars are located and incidentally to the forwardshifting movement imparted to the carriage as heretofore described. Thewidth of the bar, that is the length of the grooves need be sufficientonly to accommodate a. limited number of the bars, since it has beenfound that if the first couple bars are held against shifting thelocating of successive bars will not disturb the distributed body ofbars in the rear portion of the trough.

For finally alining the matrices that are assembled or located over thecasting slot, it being requisite that such alinement be performed withcare, we utilize a spline 78 that is adapted to enter into the slots 11which it has been explained are cut in the upper edges of the bars. Thisspline is formed on the under side of a slide 79 transversely mounted inthe bed of the machine just back of the trough in which the matrix barsare supported, such slide being alined with the casting slot in thebottom of the trough, so that, when the slide is brought forward, itwill enter the alined series of slots in the distributed bars which arelocated over such slot as shown in Figs. 9 and 12.

Slide 79 carrying the spline 78 is adapted to be thus actuated forwardlyto aline the bars by means of a lever 80 which is pivotally mounted onan axis 81 at right angles to this slide and connected by a series ofgears 82 with a pinion 83 that meshes with a rack 84 on the slide.Accordingly, when the lever is depressed from the position shown forexample in Fig. the slide and spline will be simultaneously advanced.

Lever 80 also carries means for pressing the spline 78 after it is thusadvanced, forcibly against the bars and for locking the parts in suchposition. The means in question comprise a latch 85 pivotally attachedto the upper face of the lever whereby the latter may be held either inthe elevated position shown in Fig. 3 by engagement with a notch 86 inthe supporting standard of the lever, or in its lower depressed positionby engagement with a second notch 87 in said standard. A spring 88 tendsto force the latch into engagement with whichever notch is adjacent theend of the latter. Pivoted to the lever 80 near its outer end is amember 89 that is formed with a foot of the form clearly shown in Fig.4, such foot being disposed to engage or straddle the splined portion ofthe slide 79 in the advanced position of the latter, as shown in Fig. 9.Arranged to coact with the forward end of this member is a handledcam-member 90 that, when depressed as shown in said Fig. 4, will forcethe presser foot of member 89 down with increased pressure. the reactionof course being taken by the latch 85 which locks the lever againstmovement about its axis 81. This same cam-member 90 upon being thrownback (to the left in Fig. 3) will engage the forward end of latch 85,and actuate said latch to release its rear end from whichever notch (86or 87) it may chance to engage. A. spring 91 tends to hold member 89against cammember 90.

Since it will be desirable to arrange for the reciprocation of the rack38 and slide 28, through which the shifting of the successive matrixbars is eifected in the operation of distributing the bars to compose aline, as rapidly as an operator can manipulate the keys of the keyboardto disengage and thus locate successive bars, such slide may have toreciprocate at a fairly rapid rate. The momentum thus imparted to thesuccessive bars as they are picked up by the catches and carriedinwardly across the casting slot may be such as to carry the pinsthereon past the appropriate grooves 76 in the composer plate 75, whichas above described;

has as its function to preliminarily determine the position of thedistributed bars. Means are accordingly provided to instantly arrest themovement of a bar, upon its pin being disengaged by the shiftingmechanism. Such means in the present illustrated form of the machinecomprise a series of serrated bars 95 extending continuously along therear edge of the carriage or platform 25 so as to lie just above theupper edges of the bars and in front of the portion of the slide 28 towhich the catches 27 and the members for actuating the same areattached. The serrated bars 95 overlap terminally so as to present acontinuous series of notches or serrations, but said bars areindividually pressed outwardly by the action of compression springs 96on plungers 97, which latter are. pivotally attached to said bars asshown in detail in Figs. (3 and 7.

As the slide 28 moves back and forth, it serves to press these serratedbars back out of the way, but as fast as they are uncovered followingthe passage of the slide they are urged forward by their springs intoposition to engage the pin on the adjacent bar. The result, in otherwords, is that when either catch is raised to releasea pin engagedthereby, such pin is instantly caught in a notch in the adjacentserrated bar. Thus, not only is any tendency of the bar to keep onmoving by reason of its acquired momentum prevented, but the pin is heldand forced into the appropriate groove 70 in the composer bar 75 as thelatter moves forward with the carriagc.

The general mode of operation of our improved typograph mechanism shouldbe evident from the foregoing description of its several componentparts, since the operation of each of these has been indicatedincidentally to setting forth the structural features of such part. Suchgeneral operation may nevertheless be briefly reviewed to advantage.

lnitially to arranging, or composing,a line of matrices for casting atype-bar or slug,

the two groups of'bars which compose the entire body used in the machinewill be collected in the respective ends of the trough in the conditionin which the majority of such bars are shown in Fig. 2. The drivingmechanism for reciprocating the rack is then connected by throwing inthe clutch 48, and as a result the slide 28 on the carriage or platformwill have imparted to it a corresponding reciprocating movement. It willbe understood that such carriage or platform at the start-off is locatedin its extreme rear position as shown in Figs. 1 and 3, and that theblock 13 in the front wall of the trough is likewise in its extreme rearpositionin which it is substantially shown in Fig. 2; also that thespline-slide 79 is retracted andthe lever 80 raised. As the slide 28reaches its limit of movement, say to the right of the machine as shownin Fig. 1, the corresponding catch 27 will engage the pin 30 of the barnext to the rear wall of the trough in the group of bars at that end ofthe trough. The movement of the slide now being reversed, the bar thusengaged will be carried to the left until the catch is thrown out ofengagement with such matrix-bar pin by the rear end of one or the otherof the keys (30, the operator having in the meantime depressed the keycorresponding with the first character which is desired in the linebeing composed. At the same time that the matrix-bar is thus released inselected position, the key 60 is restored to its normal position by theaction of the cam 64 on the corresponding locking member (32. Themovement of the slide 28 to the left continues, until the end of suchmovement is reached, whereupon the first bar of the group at the left ofthe trough is engaged and carried forward over the casting slot upon themovement of the slide being reversed. This bar is also left in selectedposition by the action of a key-actuated plunger, and so the operationis continued, a bar being located incidentally to each reciprocation ofthe slide by depressing an appropriate key.

\Vhere it is desired to leave an adjustable blank space in the linebeing composed, one, or preferably both keys 61 will be struck and thustwo successive matrix bars will be moved only a short distance fromtheir normal positions so that their pointed ends will extend across thecasting slot (and overlap in the case of two bars being used). The spaceis then subsequently justified by forcing such bars inwardly with-thehandled blades 70. If, however, a predetermined space is desired a baris located with one of the blank spaces further along on its under edgedefinitely in place over the casting slot by depressing the proper key60.

When a line has been entirely composed, the carriage will be drawnforwardly so as to uncover the distributed body of bars, and

thereupon the lever 80 depressed, simultaneously advancing the spline 78into engagement with the slots 11 in the matrix-bars located immediatelyover the casting slot. With the lever latched in its depressed position,a turn of the handled cam 90 will force the presser foot 89 against ,thespline-slide 79, thus locking the bars securely in place; At the sametime by actuating the lever 18 at the front of the machine, the block 13is forced in to compress the bars laterally. The type-bar or slug isthen cast by forcing metal from the pot into the slot in the 'mold, asneed not be further described. The next step is to release the body ofmatrix-bars, clamped in the fashion just described, by withdrawing theblock 13 a trifle and unlatching and raising the lever 80. The handledblades are then utilized in sweeping the respective groups of bars backinto normal collected condition in the respective ends of the trough,whereupon the machine is ready for operation to cast another type bar orslug.

From the foregoing description it will be obvious that all theadvantages inherent in the use of a loose body of matrix bars independently shiftable for the purpose of composition and justification asin the Ludlow typograph, are retained in the present improved machine.At the same time the actual manual handling of the bars is eliminated,this being mechanically efi'ected, and all the operator needs to do isto control such handling by means of the keyboard. There are nocomplicated parts to get out of order, and every portion of themechanism is readily accessible for inspection and adjustment. Thearrangement of the bars in fact presents a decided improvement in itselfover the Ludlow typograph as at present on the market, for by collectingthe undistributed bars in two separate groups instead of a single group,as heretofore, we avoid the necessity of shifting such entire body ofbars, an improvement that is of equal importance irrespective of whetherthe power shifting and keyboard locating means be used or not.
